20.500.12556/DiRROS-28855 The stress–strain state in the pelvis during sit-to-stand transfer To achieve early mobilization of patients with unstable pelvic fractures, the osteosynthesis methods used must withstand the loads in the pelvis during everyday movements. There is currently no predictive tool to assess how suitable these methods are for this purpose. The development of such a tool requires an understanding of the effects of joint and muscle loads on the structural behavior of the pelvis during movement. To further this cause, the stress–strain state of the pelvis during a sit-to-stand transfer of a healthy adult male was analyzed. Muscle and joint reaction forces during the motion were predicted using a rigid-body musculoskeletal model. These loads were then utilized in the first-ever dynamic structural analysis of the pelvis during a sit-to-stand transfer using the finite element method. Several similarities in stress distributions during sit-to-stand transfer, gait, and standing were identified by comparing the finite element analysis results with literature. The common areas of increased stress between the three motions are the acetabular notch, the superior edge of the obturator foramen, the attachments of the gluteus maximus on the ilium, and the lesser sciatic notch. The results also provide important insights into global behavior of the pelvic ring and indicate the locations of concentrated stress during sit-to-stand transfer. pelvis structural analysis sit-to-stand transfer finite element method inverse dynamics muscle forces medenica strukturna analiza vstajanje iz sedečega položaja metoda končnih elementov inverzna dinamika sile mišic true false true Angleški jezik Slovenski jezik Neznano 2026-04-09 13:25:43 2026-04-09 13:25:44 2026-04-10 03:55:40 0000-00-00 00:00:00 2025 0 0 Nasl. z nasl. zaslona; Opis vira z dne 5. 2. 2026; 17 str. issue 12, [article no.] 1328 Vol. 12 2025 0000-00-00 Zaloznikova Objavljeno apc 0000-00-00 0000-00-00 0000-00-00 616.718.19:658.5 2306-5354 10.3390/bioengineering12121328 267440131 RAZ_Znidarsic_Urban_2025.pdf RAZ_Znidarsic_Urban_2025.pdf 1 FB4406C71148BD4476D96C1285AEFE19 84dfdf5ef6dbe1fdc1009d3cc9b3cbde775e60734e9da64a60cca15920f1e8f0 01e07ab5-3407-11f1-b941-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=43006 https://www.mdpi.com/2306-5354/12/12/1328 1 dabe90c7-3406-11f1-b941-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=43005 Univerzitetni klinični center Ljubljana 0 0 0
